HYDROCARBON-BURNER.

i ,marea Specification of Letters Patent.

Patented June 22, 19115.

Application tiled August 17, 1914. Serial No. 857,018.

To all whom it may concern Be it known that T, ALGERNolT V. SMITH, a citizen of the United States, residing at Houston Heights, in the county of Harris and State of TeXas, have invented certain new and useful Improvements in Hydrocarbon-Burners, of which the following is a specification.

This invention relates to new and useful improvements in a hydro-carbon burner, and is designed particularly to be used for furnaces of stationary boilers, although it may be used at any place where hydro carbon is used as a fuel.

The object of the invention is to provide a burner of the character described, vwhereby the fuel oil is discharged into the furnace and sprayed by means of a pneumatic jet or current, which issues from the burner around the fuel jet.

Another feature of the invention residesy in the provision of an easy method of adjustment of the fuel nozzle relative to the discharge nozzle of the burner.

A further feature of the invention resides in the simplicity of the structure and the ease with which it may be separated or assembled.

With the above and other objects in view, the invention has particular relation to certain novel features of construction, arrangement of parts and use, an example of which is given in this specification and illustrated in the accompanying drawings wherein Figure 1, is a side elevation of thecomplete device; Fig. 2, is .a horizontal sec` tional view thereof, and Fig. 3, is a horizontal sectional view of the burner nozzle, shown in the position it would assume when the device is being assembled.

Referring now more particularly to the drawings, the numeral 1 refers to the body of the burner, one end of which is open and interiorly threaded as at 2, and the other end of which is reduced and formed into a tubular member 3. Through this tubular havin The pipe 4 passes loosely through the tubular member 3 but is secured therein by means of the nuts 6 and 7, which are threaded on to the section 5 of the oil discharge pipe d and rest against the respective ends of the tubular member 3. The inner end of the oil discharge pipe 4 is interiorly threaded and receives the exteriorly threaded neck 8 of the fuel nozzlef). This nozzle is flared as shown in Fig. l, but tapers in the form of a wedge to its discharge and is provided with an oblong discharge orifice 10, through which the fuel issues in a thin sheet. Surrounding the fuel nozzle is the burner nozzle 11, which, in general contour, is of the same shape as the fuel nozzle and which surrounds said fuel nozzle and is supported .by being screwed into the open end of the'body l, and the free end of the burner nozzle projects beyond the free end of the.

fuel nozzle and has the oblong discharge orifice 12 in alinement with the oblong discharge orifice 10.

A steam pipe 13 leads from a suitable source of supplv (not shown) and cornmunicates with the interior chamber of the body 1, and the steam, under pressure, is forced out in a thin sheet through the oblong discharge orifice 12, the fuel is forced, under pressure, through the fuel nozzle 9 and is carried through the orifice 12 by the 'steam pressure and is sprayed therefrom in a thin sheet of spray into the furnace where combustion takes place. The fuel being thoroughly sprayed, is readily combustible and is completely consumed without waste.

It is obvious that the relative position of the fuel nozzle to the burner nozzle, will determine the thoroughness of the mixture of the fuel in the form of spray, with the steam in the combustion chamber and for that reason the fuel nozzle has been arranged so that it will be adjustable relative to the burner nozzle. This adjustment may be accomplished by means of the nuts 6 and 7, as is readily obvious from an inspection )f Fig. 2.

In assembling the parts of the.device,the fuel nozzle 9 is first placed in position in the burner nozzle 11, in the manner shown in Fi 3, and the oil discharge pipe 4, is then Xed in position in the body 1, as hereinbefore described. The body 1, is then screwed on to the burner nozzle 11, the inner end of the pipe 4 simultaneously screwing on to the neck 8. For the purpose of the insertion of the fuel nozzle, the burner nozzle is split back a distance from-its discharge orifice so tlfat it may be opened for the admission of the fuel nozzle, as shown in Fig. 3. After the fuel nozzle has been fixed in position, the discharge end of the burner nozzle is then forced together into its original position and brazed above and below, as shown in Fig. 2.

While I have shown only one form of this burner, it is obvious that the mechanical structurethereof may be varied without departing from the principle of the invention, and I hereby reserve the right to make such mechanical changes in the structure thereof as do not depart from the scope of the appended claims.

What I claim is:

`1. A hydro-carbon burner, including a fuel pipe and a fuel nozzle secured to the free end thereof, said nozzle being flared laterally and tapered toward its discharge end, a burner nozzle conforming in shapeto and surrounding the fuel nozzle and being spaced therefrom,'said burner nozzle pro jecting beyond the fuel nozzle and having a dlscharge orifice in alinement with the discharge orifice of the burner nozzle and a pneumatic pressure inlet communicating with the interior of the burner nozzle.

- 2. A hydro-carbon burner, including a fuel inlet and a fuel nozzle secured to the free end thereof, said nozzle being fiared laterally and tapered toward its dlscharge end, a burner nozzle conforming in shape to and surrounding the fuel nozzle, and being spaced therefrom, said burner nozzle projecting beyond the fuel nozzle and having a discharge orice in alinement with the discharge orifice of the burner nozzle, a pneumatic pressure inlet communicating with the interior of the burner nozzle and means for adjusting the fuel nozzle relative to the burner nozzle.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
